Canada: Lafarge Canada has engaged Canadian Utilities on a virtual power purchase agreement (VPPA) basis to supply solar energy for its Exshaw cement plant in Alberta. Under the agreement, the Exshaw cement plant will receive 100% of energy generated at the 38.5MW Empress solar power plant in Cypress County. The VPPA lasts until 2036, and covers 34% of the Exshaw plant’s energy consumption up to that time.

Lafarge Canada (West) president and CEO Brad Kohl said "We're continually assessing ways we can reduce our environmental impact while actively pursuing sustainable solutions within our operations." He concluded "Our collaboration with Atco underscores our commitment to adopting renewable energy at our plants and sites, which is key to reducing our reliance on fossil fuels."

UK: Holcim subsidiary Aggregate Industries has installed Driver Status Monitoring Systems supplied by Spillard Vehicle Safety Systems in the cabins of its Cauldon cement plant truck fleet. The systems use cameras and AI software to detect signs of tiredness, as well as mobile phone use, lane deviation, not wearing a seatbelt and smoking. In the case of tiredness, this triggers an alarm which continues to sound until the vehicle comes to a stop.

Cement supply chain manager Matt Owen said “Health and safety is a massive priority for us as a company and the industry, so anything that can serve to continuously improve our approach to it is very welcome. Driver fatigue is always a potential issue across any business involved in transport and fleet, so we’re delighted to be utilising the latest technology with our partners to ensure that everyone gets safely home from work.”

Kenya: East African Portland Cement (EAPCC) has raised the price of its 50kg bags of cement by around 3%. It said that it made the decision due to higher input costs, according to the Standard newspaper. In a statement David Kilonzo, acting head of commercial at EAPCC, said “Due to the continuous surge in raw materials prices, operating overheads and our commitment to maintain the premium brand quality that our customers have enjoyed over the years, we will be revising our prices upwards.”

Switzerland-based Holcim holds a 42% stake in EAPC through its subsidiaries, the National Social Security Fund (NSSF) holds a 27% stake and the Kenyan government, through the National Treasury, holds a 25% share in the company.

Taiwan Cement has just commissioned a 107MWh energy storage project at its Yingde plant in Guangdong province, China. Subsidiary NHOA Energy worked on the installation and has been promoting it this week. The battery storage works in conjunction with a 42MW waste heat recovery (WHR) unit, a 8MWp solar photovoltaic unit and a proprietary energy management system. It is expected to store about 46,000MWh/yr of electricity and save just under US$3m/yr in electricity costs.

NHOA Energy, formerly known as Engie EPS before Taiwan Cement bought a majority stake in it, claims it is one of the largest industrial microgrids in the world. We can’t verify this for sure, but it is definitely large. For comparison, the 750MW Vistra Moss Landing Energy Storage Facility in California often gets cited as the largest such facility in the world. This is run by a power company, as are many other large battery energy storage systems. In its annual report for 2022 Taiwan Cement said it was planning to using NHOA’s technology to build seven other large-scale energy storage projects at sites in Taiwan including its integrated Suao, Ho-Ping and Hualien cement plants.

The aim here appears to be supplying renewable electricity to the national grid in Taiwan. Taiwan Cement is diversifying away from cement production, with an aim to derive over 50% of its revenues from other activities besides cement by 2025. In 2022 cement and concrete represented 68% of its sales, while its electricity and energy division, including power supply and rechargeable lithium-ion batteries, represented 29%. The company is also not using its own batteries at the Yingde plant. Instead it is using lithium iron phosphate batteries supplied by Ningde Times. This is worth noting, as the cement producer’s batteries are used in vehicles.

Global Cement regularly reports news stories on cement plants that are building photovoltaic solar power arrays. However, so far at least, energy storage projects at scale have been rarer. One earlier example of an energy storage system loosely associated with a cement plant includes the now decommissioned Tehachapi Energy Storage Project that was situated next to the Tehachapi cement plant in California. That project tested using lithium ion batteries to improve grid performance and integrate intermittent generation from nearby wind farms. It is also worth noting that Sumitomo Osaka Cement’s sister company Sumitomo Electric is one of the world’s larger manufacturers of flow batteries, although no installation at a cement plant appears to have happened yet. In simple terms, flow batteries are an alternative to lithium ion batteries that don’t store as much energy but last longer.

More recently, Lucky Cement in Pakistan started commercial operation of a 34MW solar power plant with a 5.59MWh energy storage unit at its Pezu plant in Khyber Pakhtunkhwa in late 2022. Reon Energy provided the equipment including a lithium-ion based battery approach to the storage. Then, in March 2023, Holcim US said that it was working with TotalEnergies to build solar power capacity and a battery energy storage unit at the Florence cement plant in Colorado. TotalEnergies will install, maintain and operate a 33MW DC ground-mounted solar array and a 38.5MWh battery energy storage system at the site. Operation of the renewable energy system is expected to start in 2025.

Away from electrical batteries, the other approach to energy storage at cement plants that has received attention recently from several quite different companies has been thermal batteries. The two prominent groups using them at different scales are Rondo Energy and Synhelion. The former company has developed its Heat Battery technology, which uses refractory bricks to absorb intermittent renewable energy and then supply the energy back as a steady stream of hot gas for use in a cement plant mill, dryer, calciner or kiln. Both Siam Cement Group (SCG) and Titan Cement have invested in Rondo Energy. In July 2023 SCG and Rondo Energy said that they were planning to expand the production capacity of a heat battery storage unit at a SCG plant to 90GWh/yr. Synhelion, meanwhile, has been working with Cemex on using concentrated solar power to manufacture clinker. It achieved this on an ‘industrially viable scale’ in August 2023. It has since been reported that the companies are working on building a small scale industrial plant at Móstoles near Madrid by 2026. Crucially for this discussion though, the process also uses a thermal energy storage unit filled with ceramic refractory material to allow thermal energy to be released at night, and thus ensure continuous operation.

The examples above demonstrate that some cement companies are actively testing out storing energy at scale. Whilst this will not solve the cement sector’s process emissions, it does potentially start to make using renewable energy sources more reliable and reduce the variable costs of renewable power. Whether it catches on remains to be seen. Most of these kinds of projects have been run by power companies and that is where it may stay. It is instructive to note that Reon Energy was the only company to state that its battery-based energy storage system has a life-span of 8 - 12 years. Our current vision of a net-zero future points to high electrical usage but it may be shaped by how good the batteries are… from our phones to our cars to our cement plants.

Mexico: Holcim Mexico says that its supply of cement to the government’s Tren Maya railway project is 170,000t/month. This corresponds to 50 – 60% of its total production volumes. Local press has reported that construction of the 1500km-long Tren Maya railway will consume 1Mm³ of concrete. Holcim supplied its cement for Sections 1 – 3 of the line between 2020 and 2022. It is currently supplying Section 5, which is 50% complete. The cement comes from the company’s Orizaba, Veracruz, plant; its Macuspana, Tabasco, plant and its Mérida, Yucatán, plant.

Holcim Mexico’s infrastructure development manager Fernando Roldan said "Our participation has been a challenge, but the relationship we have with the suppliers and with the construction companies in charge of the railway has allowed us to meet the requirements."

Oman: Tarek Talaat has moved from Egypt-based Misr Cement Group to Raysut Cement, where he takes over the role of CEO. He was previously managing director and CEO of Misr Cement Group. Before that, he held leadership positions across Europe, Egypt and the Middle East at Holcim, Arabian Cement Company and Ras Al Khaimah White Cement. Raysut Cement called Talaat the ‘standout’ choice for the CEO position, due to his vision, strategic mindset and proven turn-around experience. Tarek holds a bachelor’s degree in civil engineering from Cairo University and studied financial management at INSEAD University in France. He has a Master of Business Administration (MBA) degree from the Swiss Business School, Zurich, in Switzerland.

Raysut Cement said “With Mr Tarek at the helm, we are confident that Raysut Cement will continue to thrive and reach new heights. His leadership will be instrumental in guiding the company through the ever-evolving landscape of the cement industry.”

Reuters has reported that Talaat’s resignation as managing director of Misr Cement Group will take effect on 12 October 2023.

Switzerland: Holcim has invested in CO₂ mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO₂ by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO₂ removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to work towards achieving net zero.

Holcim’s Europe regional head Miljan Gutovic said "At Holcim, we are working to decarbonise building for a net zero future, and Neustark's technology helps us reach this goal. After the successful demonstration of Neustark's solution in Switzerland, we are ready to scale up this carbon removal technology globally."

Argentina: Holcim Argentina has awarded a contract to 360Energy to supply 30,000MWh/yr of electricity from its solar power plants. La Voz del Interior newspaper has reported that 360Energy will supply the energy from its 200MW network via the Renewable Energy Term Market (MATER). This will cover 75% of Holcim Argentina’s power consumption, corresponding to the production of 2.7Mt of cement. This will eliminate 68,600t/yr of CO₂.

Holcim Argentina chief executive officer Christian Dedeu said “I am very happy because we are taking a new step in our commitment to zero emissions in Holcim's operations, and we will continue working every day to build progress for people and the planet.”

US: Holcim US has rebranded its businesses in Boston, Massachusetts, to unite them under the Holcim name. Resources News has reported that Lafarge Cement, which operates the Charlestown cement terminal, as well as building materials producer Aggregate Industries, will rebrand as Holcim US.

Holcim US’ Northeast and Great Lakes regional senior vice president and general manager Domenico D'Aqui said "With the integration of local legacy operations into Holcim, the Boston area will see expanded benefits of construction projects made from innovative materials, such as ECOPact reduced-CO₂ concrete, that not only build needed infrastructure but also meet ambitious sustainability targets."

Philippines: Holcim plans for its subsidiary Holderfin to make a tender offer for all remaining shares in Holcim Philippines by 28 September 2023. Altogether, minority shareholders control a 5.1% stake in the producer. The Manila Bulletin newspaper has reported that Holderfin ended its previous tranche of tenders for Holcim Philippines shares on 30 August 2023.
